Origin of Mongolian Beef?

Regardless of the name of this dish, Mongolian beef did not originate from Mongolia. In fact, they created Mongolian beef Taiwan. They have adapted Mongolian beef from Mongolian barbecue restaurants. Whereby, they serve a meat and vegetable dish stir fried on a hot iron griddle at really high temperature. Equally, Taiwanese chefs invented the Mongolian beef and Mongolian barbecue dishes. And they have no associations with Mongolian cuisine at all.

What is Coconut Aminos?

Many people often use coconut aminos or coconut amino sauce as a healthier alternative to soy sauce. They mainly replace it in Asian dishes. Consequently, they made coconut aminos with coconut nectar or sap. Then aged by naturally fermenting it with added sea salt. Coconut aminos is not only a healthier replacement condiment with 70% less sodium and sweeter than standard soy sauce. It is also low calorie, low glycemic and allergy friendly. In addition, it is gluten free, soy free, non-GMO, paleo, kosher, vegan, certified organic and MSG free.

Furthermore, coconut aminos has a nice balance of sweet, savoury, rich, buttery flavour. Typically, they use coconut aminos in stir fries, stews, braises, casserole, dressings, dipping sauce and marinade. Additionally, they usually use coconut nectar or sap to make a mixture of foodstuff. For example, syrup, sugar, vinegar and other sauces in Southeast Asia. You can buy coconut aminos in health food stores or online stores. You need to store the coconut aminos in the fridge once you open the bottle.

History of Zucchini

Zucchini or courgette (Cucurbita pepo) is a summer squash that belongs to the gourd family, Cucurbitaceae. Just like all squash and pumpkin. Farmers usually harvest immature zucchini with soft and tender edible skin before their rinds harden. Just like pumpkin and butternut squash, winter squash that have hard and inedible skin. Zucchini skin is most commonly dark green but can also come in light green. Moreover, a related hybrid, the golden zucchini can be orange or deep yellow in colour.

Eventhough, botanically they consider zucchini as fruits. Because they came from a flowering plant, chefs consider them as a vegetable in the culinary world. We refer to them as botanical berry named “pepo”, meaning the enlarged ovary of the zucchini flower. The historical squash originated from Central and South Americas more than 7,000 years ago. While they cultivated the modern day variety of the zucchini initially in Italy during the 19th century. Subsequently introduced into the United States in the 1920s by European immigrants.
